Musical Hallucinosis: Auditory Illusions After Hearing Loss and Cochlear Implantation.

Bruce H Dobkin

PMID 40537459

WHAT IT FOUND

An academic neurologist with hearing loss developed continuous musical hallucinations after cochlear implantation.

The phantom choir persisted for over two years despite medication trials. White noise masking provided temporary relief, but no treatment eliminated the hallucinations or their impact on sleep.

Key findings

01The author experienced continuous musical hallucinations starting one month after cochlear implant activation, which persisted for over two years.

02Medication trials and attempts to ignore the hallucinations failed to stop the phantom singing, though white noise masking provided temporary relief.

03Surveys suggest musical hallucinations occur in a minority of cochlear implant recipients, often on the implanted side, and are frequently not reported to clinicians.

What it does not show

This is a single case report and cannot determine how common or severe these experiences are for other patients. The author is a neurologist, which may influence their detailed self-observation and interpretation compared to a typical patient. The paper does not provide a standardized treatment protocol or evidence for the efficacy of the masking strategies used. The mechanisms proposed are theoretical and based on limited experimental literature.

Declared interests

The author declared no conflicts of interest and received no financial support for this work.

The easy way to misread this

Do not assume this case represents the typical experience of all cochlear implant recipients. While surveys show a notable percentage report hallucinations, many are pre-existing, mild, or transient, and this single severe, continuous case should not be generalized to imply that musical hallucinations are an inevitable or unmanageable outcome of implantation.
